Britain is running out of time to prepare for war without a fully costed plan to defend the country, military insiders have warned.

Delays to the Defence Investment Plan (DIP), in which the Government will set out how it intends to spend money on new kit and capabilities for the Armed Forces, is hampering the UK’s ability to get ready for a major conflict with Russia or another adversary.

The warnings coincide with the one-year anniversary of the Strategic Defence Review, which set out what the UK needs to get battle ready.

On Monday Defence Secretary John Healey said the DIP would be published before the Nato summit in Ankara on 7 July.
